By using this page you can work out the duty that's been 'avoided' by home brewing!
I split the numbers into 4000 gallons of beer and 2724 of wine (haven't added up the totals in the thread, just guesstimated) and using the default settings of £2.95 a pint and £4.99 a bottle of wine the forum has avoided £737,152 of beer tax and £1,631,188 of wine tax!
Those numbers are so staggering that I don't know if I've made a mistake somewhere. Maybe someone who is more mathematically minded wants to work it out?
Maybe we're the reason the country is still in recession!! :lol:
